Invert Y axis

[thibaudtourneur]

Please, controls are hell to me. I'm a airplane control accustomed, for me to push (the mouse up) is to look down. It's not universal, but for all of us that play other games like that, it's hell switching to-/from- another game that doesn't. Please, it's just -1 sign in matrix and an option to put in a configuration file for starters (in lack of a proper GUI to do so).

Could you please add (even a minimal) support to invert the Y-axis? Thanks in advance!
